Impact of visceral obesity on operative outcomes of laparoscopic nephrectomy: comparison between visceral fat area and body mass index

摘要

Background:Obesity has been considered as a risk factor influencing operative difficulty. It was reported that body mass index (BMI; kg/m2) did not always properly reflect the degree of a patient’s visceral fat. The purpose of this study is to retrospectively investigate the association of operative outcomes and obesity indices including visceral fat area (VFA; cm2) and BMI in retroperitoneoscopic nephrectomy (RN).MethodsWe retrospectively reviewed consecutive 96 RN procedures performed from September 2016 to June 2020. We divided patients into BMI obese group (BMI?≥?25, n?=?25) and BMI normal group (BMI?
